That is simply the IBM SMTP Server/MSF telling you the email wasn't
delivered (for one reason or another).

If you have a mail server set up properly in CHGSMTPA then it's saying it
couldn't deliver to that. If you don't have a mail server set up (which
you should... <smile>) then it's saying it couldn't deliver to the end
recipient.

The "Unable to relay" is a message that came from the mail router or
recipients mail server during the message handoff.

We had a similar error a few months back. We we're using SNDDST to send
mail, relay to Exchange.
We made a change to a different Exchange server.
Only internal email was working, external email was failing.
Exchange settings had to be changed allow relay for both internal and
external email.

QGATE@xxxxxxxxxxxxxxxxxxx

NOT ABLE TO DELIVER MAIL TO SOME/ALL RECIPIENTS.
REPLY CODES WITH FIRST DIGIT = '4' OR '5' ARE ERROR REPLIES.
ERRORS THAT DO NOT HAVE ERROR REPLY CODES MAY EXIST.

HOST PENCOR06 NOT ABLE TO DELIVER MAIL TO FOLLOWING RECIPIENT(S):
<gregster@xxxxxxx>
MAIL REJECTED BY ptd WITH THE MESSAGE:
550 5.7.1 Unable to relay

This thread says that for some reason the DNS system was unable to resolve
the address (of where to send the e-mail to).

HTH,

Fellow Midrange Geeks:

Anybody know what "QGATE@<server>.<domain>" could be, in the context
of a bounce message resulting from something sent from an AS/400?

We got some bounces on messages we sent through MMAIL from our monthly
invoicing system, that we were then able to successfully resend
manually, and I've already asked Mr. Perotti about it, and it doesn't
make a lot of sense to him, either.

The bounces seem to conform to the following pattern (I've censored
the actual email addresses to "sender@xxxxxxxxxxxxxxxxx" and
"recipient@xxxxxxxxxx"):

HOST venus NOT ABLE TO DELIVER MAIL TO FOLLOWING RECIPIENT(S):
<recipient@xxxxxxxxxx>
RETRIES EXHAUSTED WHILE ATTEMPTING TO CONNECT TO REMOTE HOST domain.

** TEXT OF MAIL FOLLOWS **

and what followed was essentially the same as we'd see if we did a
"display source" on the original message.

"venus" is the AS/400 from which we're sending the automated invoices,
and "venus.private.touchtonecorp.com" matches what we see in the
CHGTCPDMN screen thereon. But I haven't a clue what
"QGATE@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" could be.
